| 目的 研究海南省疟疾空间分布特征。方法 收集 1 995～ 1 999年海南省各市 (县 )疟疾发病率资料,在ArcGIS 8.1软件支持下,建立海南省疟疾发病的地理信息系统,并以此为基础利用空间局部内插分析建立海南省疟疾空间分布图,以交叉评价指标为依据选择无偏最优的空间分布图。结果 1 995～ 1 999年海南省疟疾空间分布图显示,南部疟疾发病率显著高于北部 ;南部地区发病主要集中于五指山、鹦哥岭山脉为中心的地区,且东部沿海的发病率普遍高于西部沿海。交叉评价指标显示,建立的海南省疟疾空间分布图是对海南省疟疾分布的无偏最优估计。结论 空间局部内插法能很好估计海南省疟疾的空间分布特征,可指导相应防制措施的实施 |

| Purpose Objective to study the malaria spatial distribution characteristics of hainan province. Methods Methods to collect various cities (counties) of hainan province from 1995 to 1999, malaria incidence data with ArcGIS 8.1 software support, the establishment of hainan province malaria geographic information system, and on this basis, use of space local interpolation analysis to establish a malaria spatial distribution of hainan province, based on cross evaluation index selection unbiased optimal spatial distribution. Results The results of hainan province from 1995 to 1999 in malaria, according to the spatial distribution of malaria incidence was significantly higher than in the southern north;Southern region mainly concentrated in wuzhishan, zhao the ridge mountains as the center of the region, and the incidence of the eastern coastal is generally higher than that of the west coast. Cross evaluation indicators suggest that establish a malaria spatial distribution of hainan province is unbiased optimal estimation of the distribution of malaria in hainan province. Conclusion spatial local interpolation method can estimate the spatial distribution characteristics of hainan province, malaria, guide the implementation of the corresponding prevention measures. |
